(A) Karyotype with GTG-banding shows the absence of one chromosome 3 copy, the presence of chromosome 2 and 11 derivatives, and a marker chromosome (arrows). (B) Molecular cytogenetics analysis using whole chromosome painting for chromosomes 2 (yellow probe) and 9 (green probe) and partial chromosome painting for the 11 p (blue probe) and q (violet probe) arms. Chromosome 11p material (blue) is seen on der(2), and chromosome 2 material (yellow) is seen on the p arm of der(11). Similarly, 11q material (violet) is visible on der(3) and on the p arm of der(9). (C) FISH analysis using an MLL break-apart probe reveals 3ʹ MLL signal (red) on the der(9) (green) and 5ʹ MLL signal (green) on the der(3). (D–F) MCB analysis of chromosomes 3, 9, and 11. In each experiment, the chromosomal region are represented in colorful sequence and the nonidentified region are in gray; (D) MCB for chromosome 3 showing a normal chromosome 3 copy (3), the derivative chromosome 3 (der(3)) harboring the 3p21->3p29 chromosomal region and derivative chromosome 11 (der(11)) harboring 3p21->3p14 and 3p14->3pter regions; € MCB for chromosome 9 showing a normal chromosome 9 copy (9), the derivative chromosome 9 (der(9)) harboring 9p21∼22->qter region and der(3) harboring 9p21∼22 region; (F) MCB for chromosome 11 showing a normal chromosome 11 copy (11), and the derivative chromosome 2 (der(2)) harboring 11p14 region, the der(3) harboring 11q13->11q23 and der(9) harboring 11q23 region and the der(11) harboring the 11p14->11q13 region. (G,H) Genomic breakpoint analysis of the MLL rearrangement by Long-distance inverse PCR; analysis of the MLL gene showing the MLL-MLLT3 fusion and the reciprocal MLLT3-MLL, respectively. Letters in black represent the MLL gene sequence of (G) exon 11 and (H) intron 10, the letters in red represent the intron 5 MLLT3 gene sequence, and the letters in blue represent so-called ‘‘mini direct repeats’’ (MDRs).
